So on the actual thread topic... I never watched Supergirl S4 and am trying to catch up but I'm really struggling. The whole immigration/xenophobia metaphor with the literal alien population - whilst it's a noble message they're trying to further - is being handled with the subtlety of a hammer to the teeth and it's just not good telly

. Also, The Flash has already covered many aspects of the same topic / issues of prejudice etc. with Metahumans but in a way that was much more effectively interwoven with the overall narrative. It sort of IS the entire narrative in what I've seen of S4 Supergirl so far and it's a swing and a miss. I mean, the current villain went from an enlightened and accepting college professor telling off his ol' dad for being racist, to
a borderline Nazi, screeching "snowflake!" at an alien student, pretty much over night, because his house burned down during the Daxamite invasion. In the flashback I was expecting to see his wife or kid get killed... or at least his racist ol' dad... but no his family was all unharmed. Yes it would be awful but no one goes from peace'n'love to Human-supremacist because of a house fire!
